Infectious Disease

Unit 5

How do we get better?

Most microbes don’t cause illness. In fact, the human body has ten bacterial cells for every human cell. So, how does the body maintain itself in a microbial world? In this unit, we’ll learn how the immune system marshals its resources to outwit bacteria, viral, and parasitic pathogens. We will then highlight processes that exceptional pathogens use to evade the immune response.
